AbstractWe report on a 61-year-old female patient who developed a spontaneous spinal epidural haematoma (SSEH) after being treated by rivaroxaban, a new agent for the prevention of venous thromboembolic events in orthopaedic surgery. Although the pathogenesis of SSEH is unclear, anticoagulant therapy is a known risk factor. The patient sustained a sudden onset of severe back pain in the thoracic spine, followed by paraplegia below T8, 2 days after proximal tibial osteotomy and rivaroxaban therapy. Magnetic resonance imaging (MRI) of the whole spine demonstrated a ventral SSEH from C2 to T8. Whilst preparing for the emergency evacuation of the SSEH, the neurological symptoms recovered spontaneously 4 h after onset without surgery. After monitored bed rest for 48 h the MRI was repeated and the SSEH was no longer present. This rare condition of spinal cord compression and unusually rapid spontaneous recovery has not previously been reported following rivaroxaban therapy.
